Some non-intuitive properties of serial chemostats with and without mortality

This paper discusses a model of two interconnected chemostats in series, characterized by biomass mortality. A comparison is established with single chemostat the same total volume different cases, that are or without mortality rate. The outlet substrate concentration and biogas flow rate main criteria for comparison. According to conditions depending on operating parameters distribution volume, our results show which structure, series chemostat, performs better terms minimizing maximizing rate, this account Moreover, differences similarities corresponding case one mortality, highlighted.
